To all whom it may concern:

Be it known that I, JULIUS Donxn'rn, a subject of the German Emperor,and residing at Berlin, Germany, have invented cer- 5 tain new anduseful Improvements in Matrix-Setting and Line-Casting Machines, ofwhich the following is a specification.

My invention relates to improvements in matrix setting and line castingmachines,

and more particularly in that class of machines in which the lines arecast from a plurality of matrix bars each of which is guided to or fromthe mold holder on ways in the form of wire stretched on a frame to forma matrix carrier. Machines of this type are shown for example in thepatents of the United States to Bright Nos. 487,1 l1 and 557,184; and toRogers No. 557,232. In machines of this character such as are nowconstructed the rrame to which the rear ends of the wires are secured isslightly curved, so that the wire ends are located substantially onebeside the other within a plane which is perpendicular to the line. Withthis construction of the frame the matrix carrier must be very large, sothat a considerable force is necessary to rock the same. This isparticularly the case, where the carrier is equipped with several setsof matrices. In

this case also the length of the ways or wires and the heights at whichthe matrices fall are very large.

One of the objects of my present improvements is to so construct thesaid frame, that the size of the-carrier is considerablv reduced. Andwith this object in view my invention consists in constructing thecarrier in such a way, that the rear ends of the wires are located in aplurality of ad acent rows 40 or groups of rows.

In order that my invention may be more clearly understood severalexamples cm bodying the. same have been shown in the accompanvingdrawings, in which the same letters of reference have been used in allthe views to indicate corresponding parts.

In said drawingsFigure l, is a side view of the most simple embodimentof mv inven tion showing the machine and its wire can rier in adiagrammatical way, Fig. 2, is a plan of Fig. 1, Figs. 2 and 3 to 6, arediagrammatical plan views showing various modifications of the carrier,and Fig. 7, is a side View of Fig. 6.

Referring to the example illustrated in Figs. 1 and 2, the bed of themachine frame A and the parts mounted thereon are of any known orpreferred construction. On the machine bed a matrix carrier B has arocking support by means of pivots a. The car-- rier consists of anupright standard 8, a frame 6, and ways or wires 0 for guiding thematrix bars. At their front ends the wires 6 are secured to the standard8 and at their rear ends to the frame I). As shown in Fig. 2 the saidframe is formed with a pair of branches or side bars b Z) which arelocated one beside the other and connected at their rear ends by a yokeb so that the general form of the frame resembles that of the letter U.The rear ends of the wires are secured to the branches or side bars 6 7)of the U-shaped frame 6, so that they are arranged to two adjacent rowswhich in the example shown are parallel to each other and to the line ofset matrix bars. The wires of each group extend inwardly from their rearends in parallel relation for a suitable distance, the wires of eachgroup being arranged one above the other and merging in a commonvertical plane at the inner ends of their parallel portions, extendingforward in said common vertical plane to the standard. Near the frame F)a bow (Z is located which has likewise the form of the letter U, andwhich carries the latches for maintainin the matrix bars in theirdistributed positions.

In the example shown in Fig. 2 the branches 7), b of the frame I; aredivergent, which is preferable in this respect, that the wires at thefront ends of the branches are thereby somewhat increased in length,whereby the velocity at which the matrix bars fall downward is reduced.

In the modification shown in Fig. 3, the U-shaped frame a is broaderthan the frame shown in Figs. 1, 2 and 2 and between the branches orside bars 6 e a pair of branches c, e are provided which havesubstantially 00 the same direction therewith. Thereby four rows of wiresupports are formed which are parallel or nearly parallel to oneanother. As shown to the outer branches 6 e a larger number of wires aresecured than to the inner branches 0*, e If the matrix carrier is usedin a machine with two sets of matrix bars. the latter are preferably soarranged on the carrier, that one complete set is suspended from thewires of the right hand 1 branches, and the other one from the wires ofthe left hand branches, so that the movement of corresponding matriceson their wires requires exactly the same time in both sets. The keyboard 9 is divided, and it is provided in each section with a completeset of keys.

The example shown in Fig. 4 is similar to that shown in Fig. 3 in so faras the frame It is provided with four branches if, h, 71, k But thewires 0 are so connected to the inner branches h, if, that nearly thesame number of wires can be secured to all the branches, for whichpurpose the wires are alternately directed from the branches to oppositesides.

In the example shown in Fig. 5 the frame is provided with more than fourbranches, and it has substantially the form of a rack. As shown eightbranches 2' to a" are pro vided. In this case the number of wires whichcan be provided on the carrier is considerably higher than in theexamples described before. If now the said wires are in the ordinary wayconnected to the standard in two parallel rows, these rows would be veryhigh and therefore the matrix bars would be very long. To avoid this thewires are secured to the standard 70 in four parallel rows located onebeside the other.

While in the examples so far described all the branches. of the frameare parallel to each other and to the line of set matrix bars, or nearlyso, in the example shown in Figs. 6 and 7 only the branches located onthe same side of the carrier are parallel to each other or nearly so,while the branches located on opposite sides are at an angle to eachother. Therefore two groups of rows are formed, and the rows Z Z of theleft hand group and the rows Z Z of the right hand group arerespectively parallel to each other, or substantially so. The branches Zand Z and the branches Z and Z are respectively disposed at an angle toeach other, so as to form V-shaped sectional frames. In this case theinner sectional frames Z, Z have nearly the same size as the outer onesZ Z so that the matrices can be distributed on the carrier in adetermined way.

As appears from Fig. 7, the guide wires m of the outer frame Z Z aresecured to the lower portion of the standard 0, while the guide wires nof the inner sectional frame are secured to the upper portion of thesaid standard.

The wires or ways are arranged in groups and these groups are disposedon opposite sides of the longitudinal center line of the frame, that isto say a line extending from the standard directly rearward to the rearbar of the rocking frame. The groups on one side of this line arebalanced exactly by similar groups on the opposite side of the line. Itis not necessary that groups on the same side of the longitudinal centerline he alike or balance each other, but for each group on one side ofthe line there is preferably a corresponding group on the opposite sideof the line.- The wires in the corresponding groups on opposite sides ofthe center line are alike in number and length and inclination so thatthe frame is nicely balanced. It is also to be noted that the guidewires at their rear ends are turned laterally more or less and areconnected to the side bars of the rocking frame rather than to the rearbar thereof, this latter arrangement being the ordinary practice.

By my arrangement of the guide wires a much greater number of wires maybe placed in a given size frame and a frame carrying the usual number ofwires may be considerably smaller than when the wires are ar-- ranged inthe usual way.

I claim herein as my invention:

1. A matrix carrier for a line casting machine comprising a standard, acarrier frame provided with side bars and with forwardly projecting armsor branches within said frame, a group of matrix supporting and guidingwires connected to each of the side bars of the frame, an independentgroup of wires connected to each of the forwardly extending arms of theframe the wires of each group being carried forwardly to a commonvertical plane and continued in a common vertical plane to the standard.
